Here is a 1981 to 1985 reproduction of New Jersey's little known New car dealer sticker
These stickers were placed on new cars and were accepted by the NJ MVD as legitimate inspection stickers.
We know that they existed from 1979 to 1994.
They went on the inside drivers side window and were valid for three years on a new car but were frequently placed by dealers on late model used cars, good for one year.
